Ross Seaton designated for assignment by Astros

CHICAGO — Starting righthander Ross Seaton has been designated for assignment by the Astros.

Seaton, 23, was 2-6 with an 8.64 ERA during 11 games (10 starts) with Class AAA Oklahoma City this season. He was a third-round pick by the Astros in the 2008 MLB amateur draft. The former Second Baptist School standout has yet to make the major leagues.

Seaton’s move became necessary after Marc Krauss was added to the Astros’ 40-man roster.
